Engineered retaining walls that manage slopes, prevent erosion, and add architectural dimension to your landscape.
Retaining walls are essential structural elements for any property with grade changes, slopes, or erosion concerns. At Pedra Landscaping, we design and build retaining walls that solve real drainage and grading problems while adding architectural beauty and usable space to your yard. Whether you need a small garden terrace wall or a major engineered wall system to hold back a hillside, our team has the expertise to deliver a lasting solution.
We build retaining walls using a variety of materials -- from interlocking concrete block systems like Allan Block and Unilock to natural stone and armour stone. Each material serves different structural and aesthetic purposes, and we guide you to the right choice based on wall height, soil conditions, and the look you want. All walls over four courses include proper drainage systems behind the structure to prevent hydrostatic pressure buildup -- the number one cause of retaining wall failure.
Serving homeowners across Markham, Scarborough, North York, and the broader GTA, we build retaining walls that are engineered first and beautiful second -- because a wall that looks great but fails structurally is no wall at all.
We evaluate your slope, soil type, water flow, and wall height requirements. Walls exceeding certain heights require engineered drawings, which we coordinate.
A compacted gravel footing is installed below grade, along with perforated drain pipe and clear stone drainage behind the wall to manage water pressure.
Blocks or stones are placed course by course with proper setback, geogrid reinforcement where required, and precise alignment from base to cap.
The wall is backfilled with drainage stone and topsoil, capped with your chosen material, and integrated into the surrounding landscape with grading and plantings.
In most GTA municipalities, retaining walls over 1 metre (approximately 3.3 feet) in exposed height require a building permit and engineered drawings. Walls near property lines may also have setback requirements. We handle all permit applications and coordinate with engineers when needed.
The most common cause of retaining wall failure is water pressure building up behind the wall due to inadequate drainage. Other causes include insufficient footing, poor soil compaction, and lack of geogrid reinforcement on taller walls. Every wall we build includes proper drainage to prevent these issues.
Interlocking concrete blocks are the most popular choice for their strength, versatility, and cost-effectiveness. Natural stone and armour stone offer a more organic, high-end look. The right choice depends on wall height, aesthetic preference, and budget -- we help you weigh the options during consultation.
Absolutely. We often design retaining walls with flat, comfortable caps at seat height (around 18 inches). This creates built-in seating around patios and fire pits without adding separate furniture, making the most of your outdoor space.
Durable hardscape structures including patios, retaining walls, fire pits, and outdoor kitchens built to enhance your outdoor living.
